While most Americans are worrying about the economy, the presidential contenders shifted their attention to foreign policy.

President Obama and presumptive GOP nominee Mitt Romney spoke at the Veterans of Foreign Wars annual convention Tuesday where they made it clear that the weekend of political truce is over.

Romney accused the Obama administration of betraying America's national interests by leaking sensitive security information about U.S. operations overseas.

Sensitive details about the mission to take down Osama bin Laden and cyber warfare against Iran's nuclear program have shown up in press reports.

"Whoever provided classified information to the media seeking political advantage for the administration must be exposed, dismissed, and punished. The time for stonewalling is over," Romney said.

Romney's words come after Sen. Dianne Feinstein, D-Calif., told the World Affairs Council that some of the security leaks were coming from within the White House.

"The White House has to understand that some of this is coming from its ranks," she told the council. "I don't know specifically where, but I think they have to begin to understand that and do something about it."

Meanwhile, Romney sought to cast more dispersion on the president's record, saying, "We haven't seen much in the president's first term that inspires confidence in a second."
    
But Obama told the Veterans of Foreign Wars he's the only one in the race with a record to stand on.

"Four years ago, I made you a promise. I pledged to take the fight to our enemies and renew our leadership in the world," he said. "As president, that's what I've done. You don't just have my words, you have my deeds. You have my track record."

Obama never mentioned Romney by name, but criticized his opponent's readiness to be commander in chief in almost every example.
    
One of those examples was Romney's opposition to Obama's 2014 timeline to end the war in Afghanistan.

"When you're commander in chief, you owe the troops a plan," the president said. "You owe the country a plan. And that includes recognizing not just when to begin wars, but also how to end them."
    
Romney is on the first foreign trip of his candidacy this week. He's scheduled to make stops in the United Kingdom, Israel and Poland. The trip is described as a learning opportunity and not an effort to define his foreign policy.
